This is the nicest man who is so incredibly honest. For the item he installed for us, he guaranteed it AND, despite the fact the warranty was up in one day (which he could have just not returned our call so the warranty would expire), he happily honored it and fixed our problem. He has repeatedly helped us with our outdated unit and been more than fair with the prices he's charged us. This is a true blue person who is top notch; LOVE his work and his ethics.
